Étang Sourd (Forêt Domaniale du Montcalm) walks

The second day is a high-mountain stage passing through the highest point of this itinerary: Pic d'Estats, as well as two other peaks over 3,000 m nearby, Pic du Montcalm and Pic de Verdaguer. The route is largely over scree and rocky terrain, which will greatly appeal to mineral enthusiasts. The trail largely follows the Porta del Cel hike and the GR®T61. Although not particularly technical, this stage should not be taken lightly due to its altitude (three peaks over 3,000 metres), its length, its elevation gain and its trails composed of loose stones that can make progress difficult.

A magnificent hike in the upper Ariège in a spectacular setting. On the agenda for the day are the Etangs du Picot and the two Etangs Fourcat, which quickly make you forget the intense effort required during the climb.

First stage of the 3-day hike that is circular and loops around the Étang de Soulcem. This beautiful, long stage will take us into Catalonia, first passing by small lakes and then through the Port de Bouet, through gentle high-mountain landscapes, over the grassy, undulating slopes of the Ariège and then Catalonia; we finally reach the unmanned Josep M. Monfort Baiau refuge, which is in perfect condition and offers safe shelter (sleeps 9).

First stage of the journey through the Haute-Ariège. A beautiful, steady climb takes you to the Étang d’Izourt, steeped in human history. This is followed by a gruelling climb up to the Orri de la Caudière. Once you’ve crossed the rustic footbridge, there’s another very steep climb up to the small Étang du Fourcat. The rest of the route to the Étang du Fourcat refuge is more gentle. A very steep climb to the Fourcat refuge with an average gradient of 17 per cent. Please note: from the Étang d’Izourt to the refuge, the gradient is 24 per cent.

This is the sixth and final stage of the Tour des Géants des Trois Nations, which has a steep descent (1,800 m of elevation loss, which will hurt your joints) to return to the starting point of this journey. This stage passes by the Fourcat Waterfall, the beautiful Izourt Pond and the forests of Goulier-Auzat and Montcalm.

Before heading back, there is the option of a return trip to the Étang de Bassiès from the refuge, leaving some of your luggage at the refuge.A fairly short second stage, with two steep ascents (19% to 38%): one from the Refuge de Bassiès to the Port de Bassiès, and the even more challenging one from the Port de Saleix to the Pic de Girantès or Mont Ceint. In fact, it is a rather gruelling, up-and-down stage, classified as difficult. The ascents and descents are on challenging trails (pebbles, rocks, scree). The whole day is spent in open country with stunning panoramic views. The route passes the beautiful Étang d’Alate.The relative altitude, between 1,520 m and 2,100 m, means this day’s walk is feasible even in the height of summer.

Third stage passing through the highest point in Andorra: Pic de Comapedrosa. A high-mountain stage with no particular difficulties apart from the climb to Portella de Baiau over scree and the descent along the somewhat exposed ridge of Pic de Comapedrosa.

After our chairlift ride, we descend towards the Soulcem lake on the Ariège side. We enjoy the beauty of this glacial valley, the Soulcem lake, the Mérens horses grazing freely, not to mention the numerous orris that line the route. It is a wonderful but particularly challenging end to the hike between the Caraussans lake and the Soulcem trail.

More magnificent lakes are on the agenda, with the added bonus of a short chairlift ride on the Andorran side to rest your legs before the descent to L'Étang de Soulcem, which is very challenging in the last section.

Second stage of the route around Étang de Soulcem. A beautiful high-mountain stage with no major difficulties, despite the Port de Baiau pass, which is impressive and very steep towards the end but poses no real danger if you remain cautious. This is followed by a descent into the valley before climbing back up to spend the night at the unmanned Les Fonts refuge, a typical Andorran refuge with iron beds, a fireplace and an outdoor water point. The view over the Andorran valley is splendid and restful after the exertions of the day.
